Concentration of Pro-Health Compound of Sorghum Grain-Based Foods

More than 35% of the world sorghum seed production is a human food source. The main ingredient of fully ripe sorghum grains is starch. Sorghum does not contain gluten, and it is also a rich source of antioxidant compounds other than vitamins or macro- and microelements, including phenolic acids, flavonoids, and sterols. The aim of this study was to determine the antioxidant activity and the content of selected bioactive compounds, i.e., total phenolic acids, total flavonoids, and total phytosterols, as well as determination of the qualitative and quantitative profile of phenolic acids, flavonoids, and phytosterols in various food products, the basic ingredient of which was sorghum grain. It was found that antioxidant activity is related to the total phenolic compounds content. The ABTS•+ ranged from 319 to 885 µmol TROLOX/kg. However, white sorghum grain flour contained almost two times more polyphenols than red sorghum grain flour. The FPA ranged from 224 in raw pasta to 689 mgGAE/100 g in white sorghum grain. During this study, the quantitative profile of selected polyphenols in grain flour, wafers, pasta, and cookies containing sorghum grain was also investigated, as well as the content of 11 selected phenolic acids. Total content of the latter ranged from 445 to 2850 mg/kg. Phytosterols such as beta-sitosterol, campesterol, and stigmasterol were found in all the analyzed products. Based on this research, it was investigated that the products containing sorghum grains can be classified as functional food.

Application of X-ray computed tomography to analyze the structure of sorghum grain

Background The structural characteristics of whole sorghum kernels are known to affect end-use quality, but traditional evaluation of this structure is two-dimensional (i.e., cross section of a kernel). Current technology offers the potential to consider three-dimensional structural characteristics of grain. X-ray computed tomography (CT) presents one such opportunity to nondestructively extract quantitative data from grain caryopses which can then be related to end-use quality. Results Phenotypic measurements were extracted from CT scans of grain sorghum caryopses. Extensive phenotypic variation was found for embryo volume, endosperm hardness, endosperm texture, endosperm volume, pericarp volume, and kernel volume. CT derived estimates were strongly correlated with ground truth measurements enabling the identification of genotypes with superior structural characteristics. Conclusions Presented herein is a phenotyping pipeline developed to quantify three-dimensional structural characteristics from grain sorghum caryopses which increases the throughput efficiency of previously difficult to measure traits. Adaptation of this workflow to other small-seeded crops is possible providing new and unique opportunities for scientists to study grain in a nondestructive manner which will ultimately lead to improvements end-use quality.

For patients with celiac disease, there is a problem when compiling a diet, mainly it is the rejection of products that contain gluten in their composition. Bakeries are faced with the task of expanding the range of gluten-free products. In the manufacture of gluten-free products, non-traditional raw materials are used, such raw materials include sorghum flour. Sorghum grain is universal in use, depending on the variety, it is used both for food purposes, and for feed and industrial purposes. The purpose of the work is to study the possibility of using sorghum flour from different varieties for the production of functional gluten-free cupcakes. The analysis of the evaluation of the quality of flour and finished products was carried out by organoleptic and physico-chemical methods. The quality indicators of finished products were studied: wheat flour of the highest grade and whole-ground wheat obtained from winter wheat of the Volga Niva variety, as well as whole - ground sorghum flour from the Ros, Derzhavnoye, Vera varieties and the L-246/17 line. When determining the organoleptic and physico-chemical parameters, it was revealed that the color of the flour in the control samples was white and beige. For whole-ground sorghum flour, depending on the variety, from light beige to brown. The moisture content of the flour was normal and did not exceed 15 %. According to the fractional composition of the protein, the lowest content of glutelins was found in the L-246/17 line 7.98 %, while wheat flour of the highest grade - 31.17 %. The bakery evaluation of the finished products showed that all the cupcakes with a slightly convex crust shape are baked. The volume and specific volume of cupcakes made of whole-ground flour of the Ros, Derzhavnoye varieties and the L-246/17 line is higher compared to the control sample made of whole-ground wheat flour of the Volga Niva variety. A comparative analysis of varieties of grain sorghum for their use in the food industry, as gluten-free raw materials for the production of confectionery products is carried out

Formation of grain sorghum grain yield by different systems of shoots depending on crop fertilizer

The article highlights the main results of research conducted in the Forest-Steppe of Ukraine on typical soils of the zone – dark gray podzolic coarse-grained light loam to study the productivity of sorghum grain variety Armida. The efficiency of seed treatment with biological preparation, mineral fertilizers, foliar fertilization and nitrogen fertilization during the growing season on crop productivity was established. The combination of these components provides an increase in crop yields. The fertilizer system, which provided for the introduction of N60P60K60, turned out to be optimal for sorghum cultivation. Crop productivity with this technology was 8,49 t/ha, and for sowing seeds treated with biological preparation – increased by 32%.The productivity of the crop increased by 30,6% and with complex application – seed treatment, application of N60P60K60 in the main and application of microfertilizer in foliar fertilization, compared to the option without seed treatment (7,74 t/ha).The percentage of grain of the main shoot, panicle and tillering shoots in the biological yield of the crop is determined. It is determined that the main panicle always has a higher percentage (62,8–70,4) in the formation of crop productivity. The growth of the role of the main shoot in the formation of the overall biological yield depends on the smaller number of side shoots.

Characterizing Selected Sorghum Grain Varieties and Evaluating the Suitability of Their Malt Extracts for Cultivating Microbial Biomass

Microbial biomass is cultivated for different technological applications including food processing, medicine, waste management, and research. The conventional growth media used are generally expensive thus necessitating the development of more affordable alternatives. In this study, four sorghum grain varieties, SESO 1, SESO 3, Epuripur, and Eyera, and their malt extracts were characterized which is aimed at determining their suitability for growing microbial biomass. The varieties had kernel length, kernel width, kernel thickness, and thousand kernel weigh equivalent to 3.8-4.3 mm, 3.2-4.5 mm, 2.4-2.8 mm, and 12.4-20.2 g, respectively. SESO 1 and Epuripur had corneous endosperm textures whereas those of SESO 3 and Eyera were intermediate and floury, respectively. Varieties had germinative energies > 90 % and total defects < 8 %. SESO 3 had the highest ( p < 0.05 ) crude protein ( 10.8 ± 0.3 %) and dietary fiber ( 22.5 ± 0.4 %) whereas Epuripur had the highest ( p < 0.05 ) starch ( 81.6 ± 0.0 %) and crude fat ( 2.9 ± 0.1 %). There was no significant difference ( p > 0.05 ) in the ash contents ( 2.1 ± 0.0 %). The total sugars, free amino nitrogen, condensed tannins, and pH of the malt extracts were 106-116 g/L, 70-78 mg/L, 0.1-0.6 mg/mL, and 5.5-5.7, respectively. The composition of the sorghum malt extracts suggests their potential for use in cultivating microbial biomass.
